"SpletThe electrophysiological hallmark of JT is the presence of a His bundle electrogram that precedes the QRS complex. The HV interval is either normal or prolonged (in the setting of infra-Hisian conduction system disease). A short HV interval in association with a narrow QRS complex (<35 ms) should prompt suspicion for fascicular tachycardia. " - Short qrs interval

Our results provide a clue to the elucidation of unidentified … SpletThe R-on-T phenomenon was observed in two patients with narrow QRS complexes and repetitive supraventricular tachyarrhythmias. Case 1 had a typical Lown-Ganong-Levine syndrome in which the shortening of the P-R interval was due to a reduction of the A-H interval. In Case 2 the P-R interval (140 msec …

Splet27. okt. 2014 · Less is known about the underlying mechanism of an isolated short PR interval (i.e. no delta wave and a normal QRS complex), although this can reflect less common bypass tracts that insert directly into the His-Purkinje system. In the present study only 0.52% had short PR interval. SpletBACKGROUND: Short-term variability of the QT interval (STV QT) has been proposed as a novel electrophysiological marker for the prediction of imminent ventricular arrhythmias in animal models. Our aim is to study whether STV QT can predict imminent ventricular arrhythmias in patients.
